5 Claims.

. This invention relates in general to water closets, and more particularly to devices of this character provided for use in railwaycars and the like. A principal object of thcpresent invention is the provision of a railway water closet having a dump pan and flushing valve mechanism electrically controlled and actuated.

' Another important object of the invention is the provision of va railway water closet, the dumping or flushing of which may be readily prevented while the car is standing in a-station and without requiring the porter or other attendant to enter the room or compartment for thepurpose, I a

Another important object of the invention'is the provision of a water. closet for railway cars and the like which may be operated with minimum effort.

Another important object of the invention is the provision of an electric actuating and control I means for a railway water closet of simple construction, the parts of which may be so arranged as to make frequent repair, replacement, or readjustment unnecessary. 7

Numerous other objects and advantages of the invention will be apparent as it is better under-' stood from the following description, which,

taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is a side elevation of a water closet embodying my present invention and showing the parts in normal position;

Fig.2 is a view similar toFig. 1 showing the action of the parts in dumping;

Fig. 3 isa diagrammatic wiring layout;

Fig. 4vis a front View of a water closet, parts being broken away and shown in section to disclose the features of construction, and

Fig. 5 is a cletailof the contact devices.

A water closet shown on the drawings and in which the present invention is embodied comprises a metal stand or base 12, a ceramic bowl 13, flushing valve] mechanism 14, and the usual dump pan 15. The particular and detailed construction of these several major parts need not here be set forth.

The dump pan is pivoted at16 to swing down from the normal positionshown in Fig. 1 to the dumping position shown in Fig. 2 and back to normal position at each flushing of the toilet. A weight 17 is arranged at one end of the pivotal axis 16 of, the dump panto counterbalance it and normally support it in position to close the outlet 18 of the closet bowl. An arm 19 is fixed at the opposite end of theaxis 16 andthisarm is provided with a'pin 21 arranged in a slot 22"at the lower end of a vertically extending link 23in turn connected at 24 with a main operating lever, 25. The lever 25 at its left hand end (viewing Fig. 1) is attached to the valve operating mechanism generally indicated at 26. The opposite end of the leveris pivoted at 2.7,to a link 28 which extends down to a connection. 29 'with' a link or arm 31 fixed for 'rotation'with'agear 32.

i The gear 32 is the operating member of a chain of gears adapted to be rotatedby @anQelect'ric motor indicated generallyat 33 in motor hou'sing 34 secured upon a bracket 35 integral'withzthe m p H 70 stand 12.

Flushing of the toilet is accomplished by the mere pressing of a button or closing of the switchto complete the electric circuit to the motor. The motor and its gearing are so constructed and arranged that a complete flushing operation occurs at a single rotation of the gear 32. The link 31 moves from the position shown in Fig. 1 to the position shown in Fig. 2 to dump the dump pan and open the flushing valve to deliver water to 3 0 gear 32 back to its normal position as shown in the closet. 1 Thereafter further rotation of the Fig. 1 arranges the toilet for subsequent use.

Electric power is delivered to the motor as will now be described, reference being had particularly to Figs. 3 and 5. Line wires 36 and 37 may be considered the source of electric power. The

wire 37 is tapped in at 38 to one terminal of a 7 It leads from the terminal 38' to a fixed terminal 41 in the motor housing. A bridge 79b switch 39.

member 42 is arranged to engage the terminal 41 and a second terminal 43 in turn connected by wires 44, 45 and 46 to one of the motor terminals. The wire 36 is connected to the other motor terminal. The second terminal 47 of the switch 39 g 'is connected by a wire 48 to the wire 45. The

bridging member 42 is normally out of contact with the, terminals 41 and 4 3. It consists of the contact bar 42 which is mounted upon and insulated'from two springs 49 which serve to press fo the bridging member 42 upwardly.

A stud 51 is fixed in a collar 52 upon the shaft 53 of the gear 32 and after each dumping operation the stud 51 presses the bridge member 42 down out of contact with the pins or terminals 41 E 7) and 43 interrupting the current. When itis de-' sired .to flush the toilet, the switch 39 is closed and current then fiows to the motor through wire 3'7 of switch 39,.wires 48, 45, and 46 to the motor 1'10 and backthrough wire 36to the source.

Immediately upon the starting of the motor and the commencement of the flushing action, the post 51 moves out of engagement with the bridging member 42 and an operating circuit is completed. This circuit consists of wire 37 to post or contact'41, bridging member 42, post or contact 43, wires 44, 45, and 46 to the motor and thence back by wire 36 to the source.

A second switch 54 is, or may be provided in the circuit. The switch 39 is arranged adjacent the water closet and is the switch commonly used in the flushing; The switch 37 is, or may be arranged. outside the lavatory and when opened by 1 the porter or other train attendant, prevents flushing of the closet when the train is standing in the station.

The lever may be provided, ifdesired, with a socket 55 at its end attached to the link 28 for V the reception of a handle 56 to permit manual 20 operation if the motor be discormected.- The pin 21 and its slot connection with the link 23 permits dumping of the dump pan by the lifting of the weight and without operation of the electrical mechanism. This last is provided in order to 2V5 facilitate flushing and-cleaning oi the toilet in the yards.

i It is thought that the invention and many of dump pan normally closing the outlet of said bowl and adapted to swing to a dumping position, and

, electric means for moving said dump panto flush said bowl and return said dump pan to sealing position after flushing.

A water closet, comprising a closet bowl, a dump pan normally closing the outlet of said bowl and pivoted to swing downwardly in flushing, an electric motor and connections between said motor and said dump pan for swinging said dump pan downwardly in dumping and returning said dump pan after flushing.

4.A water closet, comprising a closet bowl, a valve mechanism for supplying flushing water to said bowl, a dump pan for closing the outlet of said bowl and movable to dump in flushing, and

an electric motor connected to said dump pan and I to said valve mechanism for operating said dump pan and said'valve mechanism in timed relatioini;

5. A water closet for railway cars and the like, comprising a closet bowl,.a dump pan closing the outlet of said bowl and movable in flushing, an

electric means for operating said dump pan, saidelectric means including a plurality .of circuitw:

closing devices, one arranged adjacent the water closet and the other at a point removed there-' from;
